Title: Digital-analog converting circuit
Inventor: IGARASHI HATSUHIDE
IPC: H03M1/78
Filed: 1981-10-26
Abstract: PURPOSE:To extend the accuracy of D/A conversion, by weighting the ON resistance of a transistor which switches a ladder-shaped resistance network in correspondence to said resistance network. CONSTITUTION:For a ladder-shaped resistance network comprising resistances R and 2R, the ON resistance of a transistor TR which switches the resistance network is set so that the ON resistance of a TRT2 may attain double when the ON resistance is set at 1 for a TRT1 at the side of an MSB. For this purpose, a necessary number of unit TRs are connected in series in oder to obtain the prescribed ON resistance at each stage. The variation of the threshold value can be eliminated if the TRs are worked in the same process. This can prevent the deterioration of the converting accuracy. At the same time, the weighting can be obtained to a current in an accurate squaring relation.
